just started to happen today, drives fine without any slipping at all. sometimes hard to get out of 1st gear and reverse only. even with the clutch pedal completely pressed in, the car still feels like the clutch is slightly engaged with a tad of jerking. only very low speed 2<mph in 1st and reverse only. checked the master cylinder which had a slight leak and has been changed. the slave is fine with no leaks at all also. bleed correctly til not no air bubbles are left at all. symptoms of a failing clutch?
